Keiser M3iX Indoor Cycling


Keiser M3i

"These are getting used more than anything else in our facility."

The M3iX is a newer addition to Keisers dynamic line of award winning indoor fitness cycles.

Combining the unique pivoting patented X-Bars to the heralded M3i Indoor Cycle makes the M3iX to mountain biking or hill climbing what the M3i is to road biking.

It has the same silky smooth ride and M3i reliability, with 7 levels of handlebar resistance. Independent upper and lower body movements offer great core, upper torso, and arm benefits and also aids balance training.

Research shows X-bars burn more calories than traditional group exercise bikes. The X-Bars offer added variety for both instructors and riders both in the classroom setting and out on the fitness floor.

Keiser M Series Indoor Bikes revolutionised the world of group fitness when they came on the market over two decades ago, and have set the standard for the category ever since.

The first bike to use eddy current magnetic resistance and an aluminium flywheel, the M Series continues to offer users and owners innovations that improve the group cycling experience.


As part of our commitment to scientific solutions for fitness, Keiser M Series Indoor Bikes are built to change the way you look at indoor cycles.

  • Rust-resistant design includes stainless steel hardware and rear flywheel

  • Revolutionary, re-designed Keiser pedal

  • Quiet and low-maintenance belt drive system, eliminating the output of dust and need for lubricant with chain-driven systems

  • Magnetic eddy current system provides infinite levels of resistance options and a smooth ride

  • Lightweight at 85 lbs. and easy to transport with two front transport wheels

  • Over 300,000 M3 field-proven group bikes in use today

  • Powertrain tested for more than 30 million cycles

  • Handlebar tested for more than 30 million cycles


The magnetic resistance system works using eddy currents: electric currents on M Series equipment are generated by two opposing magnets passing over the flywheel. By varying how much of the flywheel comes into contact with the magnetic field, resistance can be increased or decreased for the rider.

And, as no parts in the resistance system ever touch, there is no wear on the system.


As indoor group cycling grows in popularity and the demands on bikes increase, the need for a more user-friendly - yet more durable - commercial grade pedal became clear. For those who demand more from their equipment, Keiser introduces the M Series Bike Pedal.


Because the industry standard isn’t up to our standards, Keiser once again revolutionises Group Cycling down to the last detail with our game-changing Bike Pedal that will challenge the way all pedals are measured.
